Genetic duplications of 9p24.3, and therefore the DOCK8 and KANK1 genes, are associated with autism spectrum disorders (ASD), intellectual disability/developmental delay (ID/DD), attention deficit hyperactivity disorder (ADHD), epilepsy, learning problems, and language disorders (Engelhardt et al., 2009; Glessner et al., 2017; Griggs et al., 2008; Krgovic et al., 2018; Oikonomakis et al., 2016; Ruiter et al., 2007; Su, 2010). This evidence concerns the gene DOCK8 and epilepsy.
